This "implementation detail" could be used in other contexts. I
understand GDAL doesn't have for purpose to provide a XML parser. But
this function is used to convert a XML file to a StringList, which is a
GDAL object. I think it would make sens to make that function accessible.

You are right, this is not a static method. However, it only depends on
the class method "AddXMLNameValueToList" which is defined by a single
line of code. So, this method could easily be made static.

Anyway, I leave this to your good judgement, and I will adapt according
to your decision.

Best regards. Julien :)
